| 摘 要： | 在地质矿产调查、地球物理勘探中,高精度磁测以经济、实用、快捷等特点,在寻找铁磁类矿物及构造中被广泛应用,但在磁测工作中,资料预处理正常场梯度改正比较繁琐,误差又比较大,笔者通过论述和实列对比,指出了目前磁测规范中正常场梯度改正存在的问题,并对正常场梯度改正方法进行了一定的探讨,提出了精度较高的正常场梯度改正方法,同时还提出了一种快捷的磁异常计算方法,使得磁测资料预处理更加简便、准确。

| Abstract: | In geology and mineral resources survey and geophysical exploration,high-precision magnetic measurement is characterized by economic,practical,and fast,so it find a wide application in searching for ferromagnetic minerals and geological structures.However,in data pre-processing,the correction of normal field gradient is relatively complicated and has a big error.Through comparison between practical examples,we point out the problem exists in current norms of normal magnetic field gradient measurements to co... |
